Devices and systems related to an improved spinal pedicle based construct are disclosed herein along with the related method of manufacturing and operation thereof. The improved spinal pedicle based construct may include a flexible membrane(s) or mechanism(s) incorporated between the anchoring component and the longitudinal membrane. The flexible membrane(s) incorporated may provide controlled motion of the functional spine unit connected to the anchoring component with respect to the posterior construct. Moreover, when the patient moves his or her back, the flexible membrane(s) may also divert a force away from the anchoring component, thereby reducing the chances of bone cracking.
